Other Parts Discussed in Thread: MAX3232
Nowadays i met a problem on the Max3232.
i didn't understand what's the a dual charge pump on Maxim3232 used for.
the V- pin on the MAX3232 didn't gave a negative signal, so we just parallelled another Maxsim3232 for the negative signal, it seemed sometiome didn't work.
the V- pin was connected to a power amplifier as a negative power, it's too weak,how to solved this problem?
thank you very much.
